Cirrhosis can be caused by a variety of diseases, with alcohol abuse and viral hepatitis being some of the most common. This video discusses the cellular mechanism behind fibrotic tissue generation and the pathophysiology of a cirrhotic liver. It also covers some of the major complications, as well as clinical signs and symptoms.
Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
The intraperitoneal fluid, be it blood, ascites, or dialysate, collects in this space and may be visualized, most commonly via ultrasound or computed tomography (CT) scanning. As little as 30 or 40 ml of fluid in the abdominal cavity may be visualized in this space.
Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis, is an autoimmune disease of the liver. [1] [2] [3] It results from a slow, progressive destruction of the small bile ducts of the liver, causing bile and other toxins to build up in the liver, a condition called cholestasis.
In terms of HCC diagnosis, it is recommended that people with risk factors (including known chronic liver disease, cirrhosis, etc.) should receive screening ultrasounds. If the ultrasound shows a focal area that is larger than 1 centimeter in size, patients should then get a triple-phase contrast-enhanced CT or MRI scan. [17]
[27] [28] The result of an MRE scan is a quantitative 3-D map of the tissue stiffness, as well as a conventional 3-D MRI image. One strength of MRE is the resulting 3-D elasticity map, which can cover an entire organ. [2] Because MRI is not limited by air or bone, it can access some tissues ultrasound cannot, notably the brain.
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
